WH social secretary won't testify

From NBC's Savannah Guthrie and Domenico MontanaroWhite House Press Secretary Robert Gibbs says Desiree Rogers, the White House social secretary, won't be testifying before a House committee tomorrow in relation to the state dinner security breach.

And get this, the White House is citing separation of powers concerns.

Just asking, but didn't Karl Rove, et al, use that reasoning in the Bush administration -- for what some would consider a much more serious matter? And didn't liberals go nuts over that?
